Resize Pro is the fastest texture resize/scale tool for Unity. Works in Editor and Run-time.

In Editor textures can be resized directly from Project window or by using batch converter (new texture is saved in PNG or JPG formats).
Run-time API adds ResizePro() extension method to the Texture2D class.



Note:
Tool is already included in Texture Adjustments asset.

Looks nice.
Do you have benchmarks of your plugin performances?
Maybe you can compare it with this: http://wiki.unity3d.com/index.php/TextureScale

Does it work on mobile too?

 

TextureScale: Only works on ARGB32, RGB24 and Alpha8 textures that are marked readable.
ResizePro: Works with all type of textures.

TextureScale: CPU calculation + bad memory management.
ResizePro: GPU calculation + no memory problem.

Most devices (even very old) support RenderTextures, so yes, ResizePro works on mobiles too.

Here are some benchmarks.

WOW, nice perfs.
Does your benchmark graph clamped to 1 second or the plugin always wait at least 1 second?

 

After resizing pixel array is read from GPU and saved inside Texture2D. That needs some time.

is this useful in-game or just compression on the editor ?

 

Run-time API adds ResizePro() extension method to the Texture2D class.

sorry if i sounds like a beginer could you explain further

 

Adds ResizePro function to the Texture2D class:

Code (CSharp):

1. using UnityEngine;
2.  
3. //ResizePro
4. using VacuumShaders.TextureExtensions;
5.  
6.  
7. public class NewBehaviourScript : MonoBehaviour
8. {
9.     public Texture2D texture;
10.     int width;
11.     int height;
12.  
13.     void Start ()
14.     {
15.         //ResizePro
16.         texture.ResizePro(width, height);
17.     }
18. }

Hi

I am trying to use your plugin (bought it as part of TextureAdjustments) but I am not sure how to use it. I assumed it should be simple to use.

I get an texture from a filepath using WWW, and if it is too large I want to resize it. Using TextureScale I could just use

Code (CSharp):

1. TextureScale.Bilinear(texture, 4096, 4096);

So now I try using your code

Code (CSharp):

1. texture.ResizePro(texture.width/2, texture.height/2);

but the texture just shows purple, as it also does when the texture is too large. Could you please guide me in the right direction?

EDIT: The texture is resized, but the pixel information is lost. This is confirmed by writing the texture out to the disk.

 

In the description of the WWW.texture is written that variable is Read Only. You can't modify it.

In this case use:

Code (CSharp):

1. ResizePro(int width, int height, out Texture2D dstTexture)

that returns resized texture inside dstTexture variable.



VacuumShaders - Facebook Twitter YouTube

 

Cannot seem to find a ResizePro function that have those arguments within the namespace VacuumShaders.TextureAdjustments or VacuumShaders.TextureExtensions. Can only find TextureResizePro.ResizePro(Texture texture, int width, int height) and TextureResizePro.ResizePro(Texture texture, int width, int height, TextureFormat format, bool hasMipMap)

I just find it odd that you proclaim that your plugin can handle "all type of textures." when there are exceptions. Anyway if you can point me in the direction of the mentioned function that would be great!

[EDIT] I just bought the ResizePro plugin directly, and this gives me the function with the parameters you mentioned, so there is a mismatch between the "original" and the one included in Texture Adjustments.

Unfortunately it did not work, here is a code example which will give the error:

Code (CSharp):

1. WWW www = new WWW("http://kanda.dk/TestLargeImage/PANO_Field.jpg");
2.  
3. while (!www.isDone)
4. {
5.     yield return null;
6. }
7.    
8. Texture2D texture = www.texture;
9. //Max texture size on iOS
10. int textureHeightLimit = 4096;
11. int textureWidthLimit = 4096;
12. //File.WriteAllBytes(Application.dataPath+"/../SavedScreenBefore.png",texture.EncodeToPNG());
13. if (texture.height > textureHeightLimit || texture.width > textureWidthLimit)
14. {
15. #if UNITY_IOS || UNITY_EDITOR_OSX
16.     //TextureScale.Bilinear(texture, textureHeightLimit, textureWidthLimit);
17.     Texture2D theOtherTexture = new Texture2D(texture.width/2, texture.height/2);
18.     texture.ResizePro(texture.width/2, texture.height/2, out theOtherTexture);
19.     texture = theOtherTexture;
20. #endif
21. }
22. //File.WriteAllBytes(Application.dataPath+"/../SavedScreenAfter.png",texture.EncodeToPNG());
23. // continue and use the texture
24.  

 

Update Texture Adjustments to v2.21, it includes latest ResizePro API.

What exceptions?
If variable is Read Only it can not be modified directly, memory it occupies is 'locked' and can't be overwritten.

Just tried, everything works. Texture is downloaded and saved, including resized version.
What is the error?

As there was no need to purchase ResizePro, I can give refund on it.

Done

I also just tested, and found out that it works if I have Standalone set as build target, but it does not work when changing to iOS or Android as build target. I thought it might just be an editor thing, but it doesn't work on devices as well. Does it only work on standalone? I do not see any platform limitations mentioned anywhere? Could also be some settings that I need?

Sure lets find out, I have sent a mail friday last week, lets take that there.

 

What you mean by 'doesn't work' ? Some errors, warnings, exceptions, crashes ? More details will be helpful.
Also make sure target device supports RenderTextures - it is the only requirement.

The problem was that I did not get any errors, so was hard for me to find the problem. However, I did find that the problem is not ResizePro, but rather the limitation of the system that was the problem. I tried with 8k texture on iOS which does not support over 4k and this also limits the plugin.

However I did find a workaround, though it might not be pretty, it works (so far). I split the texture in 2 halfs, then resize each half and then combine them again. So having a texture of 8192 x 4096 I split in left and right each 4096 x 4096. Then resize left and right to 2048x2048. Then combine left and right to a single 4096 x 2048 image.

 

Hi. I was wondering if this would scale Texture2D objects on iOS with BGRA32 formatting?

 

It works with all Texture2D objects. No restriction on image format.

Does this support Windows Phone 8.1 ?

 

Of course.

Hello Devs, this seemed to work great, but has a memory leak issue with the following lines of code on UWP app:

Code (CSharp):

1. UnityEngine.WSA.Application.InvokeOnAppThread(() =>
2.             {
3.                 texture.LoadRawTextureData(_latestImageBytes);
4.                 texture.Apply();
5.              
6.                 int quality = 2;
7.                 Texture2D resizedTex = new Texture2D(_width / quality, _height / quality, TextureFormat.BGRA32, false);
8.                 texture.ResizePro(_width / quality, _height / quality, out resizedTex, false);
9.                
10.                 _bytesJpg = resizedTex .EncodeToJPG();
11.             }, true);

 

Do not use constructor or any kind of initialization for out parameters.
Just use:

Code (CSharp):

1.  
2. Texture2D resizedTex = null;
3. texture.ResizePro(_width / quality, _height / quality, out resizedTex, false);
4.  

and do not forget to destroy texture manually after use. Unity does not release memory allocated by texture.

Never mind, and apologies, this was due to my not explicitly disposing of the instantiated Texture on each call. Great asset!

 

THANKS!

 

Can you try these three picture?

ResizePro works fine on editor, but in iOS

1,3 is a purple texture, only 2 is success.

This is my code

Code (CSharp):

1.  
2.             var tex = new Texture2D(0, 0, TextureFormat.RGB24, false);
3.  
4.             ImageConversion.LoadImage(tex, bytes, true);
5.  
6.             var width = tex.width;
7.             var height = tex.height;
8.  
9.             if( width > 2048 || height > 2048 ) {
10.                 Debug.LogFormat("Original size = {0},{1}", width, height);
11.  
12.                 if( width >= height ) {
13.                     height = height * 2048 / width;
14.                     width = 2048;
15.                 } else {
16.                     width = width * 2048 / height;
17.                     height = 2048;
18.                 }
19.  
20.                 Debug.LogFormat("Resize to {0}, {1}", width, height);
21.  
22.                 Texture2D resizedTex = null;
23.  
24.                 tex.ResizePro(width, height, out resizedTex, false);
25.  
26.                 Destroy(tex);
27.  
28.                 return resizedTex;
29.             }
30.  
31.             return tex;

 

iOS can not handle more than 4K textures. It's hardware limitation.
1 and 3 textures resolution is more than 4K and that's why conversion fails.

But TextureScale can scale successfully.
Is there some way I can scale texture more than 4K by using ResizePro?

 

Hi on Android Huawei P8 lite and Huawei Y6 Im getting black or grey textures after resize. On Lenovo K6 (K33a48)
For sure I test small textures 1024x1024 and still same, black/gray textures, no errors or exceptions.

Do you have any tip how to debug?

Regarding what device must support... "Most devices (even very old) support RenderTextures, so yes, ResizePro works on mobiles too."

Render texture support must be tested for specific texture not only for if supported in general, see the obsolete API.
During the import of your asset there is automatic API update on your dll assembly. Without source code I cant see what changed and cant debug. So for now I cant use it.

I used following code to decide if scale on gpu can be done(_newWidth, _newHeight is smaller than input texture):

Code (CSharp):

1.  
2.             Texture2D _scaledTex = new Texture2D(_newWidth, _newHeight, TextureFormat.RGB24, false);
3.             bool supportRenderTexture = SystemInfo.SupportsRenderTextureFormat(RenderTextureFormat.ARGB32);
4.             bool maxSizeSupported = Mathf.Max(_inputTex.width, _inputTex.height) < SystemInfo.maxTextureSize;
5.             bool scaleOnGpu = false;
6.             if (maxSizeSupported && supportRenderTexture)
7.             {
8.                 scaleOnGpu = true;
9.             }
10.             UnityEngine.Debug.Log("supportRenderTexture " + supportRenderTexture + " maxSizeSupported " + maxSizeSupported + " " + _inputTex.width + "/" + _inputTex.height);
11.  
12. .. later
13.  
14.           if (scaleOnGpu)
15.             {
16.                 UnityEngine.Debug.Log("scale using ResizePro");
17.                 TextureResizePro.ResizePro(_inputTex, _newWidth, _newHeight, out _scaledTex);
18.             }
19.             else
20.             { // bilinear scale code
21.             }
22.  
23. // later _inputTex is destroyed and function return _scaledTex;
24.  

thank you for your support

Hi,

I have this message : Feature `declaration expression' cannot be used because it is not part of the C# 4.0 language specification.

Regards.

 

What is Unity version and build target?



VacuumShaders - Facebook Twitter YouTube

 

Hello, your asset will work with unity 2017.3.f3? And support tiff with zip compression?

 

It works in Unity 2017.3.0f3.
Editor exports resized textures in PNG and JPG file formats. And in TGA if this plugin is installed.



VacuumShaders - Facebook Twitter YouTube

 

Hi, Interested in ResizePro to scale down dynamically loaded images. I note that someone questioned the use of this under .Net 4+.
Can you confirm that this will work under 2017.3.0f3 with .Net 4.6 thanks.

 

Fully compatible with 2017.3.0f3
Developed with .Net 3.5 and have not found any problems using with .Net 4.6



VacuumShaders - Facebook Twitter YouTube

 

Works well - very happy - bought .
Tested using 2017.3.0f3 and .Net 4.6.

Now what can you provide to speed up Unity's EncodeToPNG()

 

Hey, does it use any kind of interpolation when scaling? For example, when scaling with GIMP I can select different interpolation types: linear, cubic, sinc.

Thank you

 

Simple rescaling, no interpolations options to choose from.



VacuumShaders - Facebook Twitter YouTube

 

Your Asset page mention:
* Has no limit on texture formats and works even with textures that aren't Read/Write enabled.

But after purchasing, your document says:
* Texture must be readable and in uncompressed format.

Wouldn't uncompressed textures on Mobile be useless? Anyhow, it seems misleading...

p.s your support email goes to a Facebook page where messages are disabled, will count the hours for a reply here!

 

Included documentation describes two methods:

If texture is unreadable (locked in memory) use the second method, after that destroy original texture.
Resized texture will be in dstTexture.

Resize Pro not working in Unity 2017.2. I keep seeing this error message in the console:

TypeLoadException: Could not load type 'VacuumShaders.TextureExtensions.ImportSettings' from assembly 'VacuumShaders.ResizePro_Editor, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'.
UnityEditor.Build.BuildPipelineInterfaces.InitializeBuildCallbacks (BuildCallbacks findFlags) (at C:/buildslave/unity/build/Editor/Mono/BuildPipeline/BuildPipelineInterfaces.cs:122)

What can I do to make this work in Unity 2017.2

 

When using Unity 2017.2 asset store downloads version for Unity 5.4
Try Unity 2017.3
(There are two versions of the asset on the store, for Unity 5.4 and Unity 2017.3)

How can i resize an texture to either maxwidth = 1000 or maxheight = 1000 (which is bigger) by maintaining aspect ratio?

so if an image is bigger like 2400x3000, it set its height to 1000 and width accordingly

Thanks

 

Update will be available tomorrow.

Hi @Arkhivrag,
Yesterday I bought both ResizePro and Texture Adjustments. Both great assets, thanks!
What would you advise to do when (at runtime) you get an image file larger than 4k that needs to be scaled down to a size that fits a Texture2D. Is there an approach that you would recommend?

 

ResizePro is Unity Texture2D extension and to use it on image it must be Texture2D object.
If you have some byte[], stream, etc containing image data ResizePro can not help. Unfortunately I can not recommend anything to resize such data. May be google for some appropriate methods.



VacuumShaders - Facebook Twitter YouTube

 

Thanks Arkhivrag,
I understand the scope of your product. And I'm very happy with the ResizePro Texture2D extension.
Because of the 4k texture limitation on iOS I had an app working perfectly inside the editor but not on iOS devices. I saw no solution inside Unity C#. I now wrote a native iOS plugin to do the image resizing. Works perfectly but if you knew of an approach that would work without native plugins that would have my preference.

 

Doesn't appear to be working on mobile in Unity 2018.1.2f1 running in Linear Color Space on Android. Tested on Samsung Galaxy S8+.

TextureResizePro.ResizePro(photoTaken, 216, 384, false);

 

What exactly does not work? If ResizePro can not resize image it prints detail info about that.
